The direct scattering study of the parametrically driven nonlinear Schr\"odinger equation
Abstract
The term "direct scattering study" refers to the calculation and analysis of the discrete eigenvalues of the associated Zakharov-Shabat (ZS) eigenvalue problem. The direct scattering study was applied to time-dependent oscillating solitons that arise as attractors in the parametrically driven nonlinear Schr\"odinger equation. Four different types of attractors within the parameter space are identified, each with a unique soliton content structure. These structures include radiation-induced nonlinear modes and soliton complex structures. The different types of attractors are used to characterise the dependence of the attractors on damping and driving parameters. Period-doubling bifurcations are shown to affect the radiation emissions of oscillating solitons. The role of soliton complex structures and radiation in the formation of spatio-temporal chaos is also identified.
